Ed,
Small world, I live up by the Old Hill Farm Dairy on Schuylkill St soon as you crest the top of the hill third house on the right.
Agh Hidden Valley brings back allot of memories. Lots of big deer back in there. Used to be able to walk across the golf course to get back in.
Times have changed and no longer able to get back in there from the golf parking lot.
I poke around out at Tumbling Run, I'm sure you know where that is
